Defining Classes

Object classes are typically defined in Caché using Caché Studio,an integrated development environment for defining object classes. Cach顯s Unified Data Architecture automatically generates tables (complete withcolumns and key fields) from all class definitions, their properties and methods. The complete definition is made using the Class Definition Language (CDL) of Caché and is stored in the database in some internal format. Export functions are available for various class definition formats commonly used in the OO world. Additionally, RoseCachéLink provides a direct bidirectional interface to Rational Rose,the visual modeling tool (based on the object-oriented standard language UML) from Rational Software.
